Application filed December 15, 1924. Serial No. 755,908.

Fig. 1 is a view in side elevation of my improved force-feed oil-can.

Fig. 2 is a View thereof in longitudinal, central section on an enlargedscale.

Fig. 3 is a sectional View on the line 33 of Fig. 2, but omitting thespring.

Fig. 4 is an underside view of the cap and spout, with the springassembled therewith.

My invention relates to an improvement in force-feed oil-cans, theobject being to shown, I form, upon the body 5 of the can,

a sufiiciently large and long, cylindrical neck 6 to provide apiston-chamber 7 in which I locate a piston 8 substantiallycorresponding to it in diameter and co-acting directly with the innerfaces of its sidewalls, i. e.. with the side-walls of the neck of thebody ofthe can. As herein shown, thesaid piston 8 is mounted betweenmetal disks 9 screwed upon the threaded upper end of a piston-rhd 10 ina-guidetube 11 mounted in the center of the recessed bottom 12 of thebody 5 of the can, the projecting lower end of the piston being,provided with the usual push-button 13. A jam-nut 14; holds thepiston-disks 8 in place upon the rod 10. The spent 15 is mounted in acap 16 having a threaded skirt 17 screwed over threads rolled into theouter end oi. the neck (3. A packing-washer l8, interposed between thecap and the inwardly-turned edge of the neck, prevents leakage.

The piston is returned into its normal position and held therein bymeans of a helical spring: 19 interposed between it and the cap 16, thelower end of the said spring being turned inwardly and then passedaxially outwardly through the spring and made long; enough, as at 20, toextend throue'h the tip of the spout when the spring is 'r 'oiupressed,whereby the spout is kept from eing: clogged.

In its normally retired position, in which it rests u n the snide-tube.1. the piston 8 is located below the curve formed in the sheetanetalbody of the can, where the. ta poring, shoulder thereof merges into itscylindrical neck 6. This curved surface is engaged by the edge of thepiston and serves to center the same as it enters the neck.

which forms the piston-chamber of the can.

In using' y improved can, it is tipped enough to cause oil to flow intothe pistonchamber 7, after which the button 13. is pushed to operatethe'piston 8 against the tension of the spring 19 in forcing the oil outof the spout. As soon as pressure uponthe button 13 is removed, thespring re-' asserts itself to retire the piston into its phargingposition, in which it is shown.- in lg. 2.

By enlarging and lengthening the neck of the body of the can, so as toadapt it to be utilized as the forcing-chamber, I avoid the complicationof employing a special cup located within the neck for the purpose.

Also, the extension of the lower end of the I spring into the spoutprovides simple means of preventing the same from being clogged.

1 am aware that force-feed oil-cans have been provided. with cleaningwires extending through their spouts for preventing the same. from beingclogged. I am also aware that the piston-ehainhers of force-feed oileanshave been located adjacent their spouts, as well as at the bottoms oftheir fonts, and that such oil-cans have been provided with helicalsprings for holding their pistons intheir retired ositions. Ido not,there fore, claim any of t iese features broadly, but

1. In a force-feed oil-can, the eolnbination with a body having acylindrical. neck merging into the body by an oblique wall and forming apiston-chamber, of a piston positioned to ,co-act directly with the saidneck, a piston-rod, the upper end of which mounts the said piston andthe lower end of which projects through the bottom of the can for itsmanual operation, a combined cap and spout applied to the outside of theforming a piston-chamber, of a piston positioned to co-act directly withthe said neck, a piston-rod, the upper end of which mounts the saidpiston and the lower end of which projects through the bottom of the canfor its manual operation, a combined cup and spout applied to theoutside-of the neck and a helical spring interposed betweemthe said capand t e upper face of the said piston for holding the latter in itsretired position,

the inner end of the spring being turned in- 10 wardly and passedaxially outward through the coil thereof and extended substantially tothe end of the said spout to act as a cleaning-wire.

In testimony whereof, I have signed this 15 specification.
